Dear Steve:

I tried to upload a couple of photos in the image section. Not sure if I loaded them correctly. This article provides a couple of nice photographs of the Olds W-43 and OW-43 engines. This “ Hot Rod Magazine Engine Annual” article from 1971 is about ten pages in length. It was a special feature on some of the Oldsmobile divisions high performance engine development of late 1969-1970. There were several other publications that did features on these and various other Oldsmobile DOHC 4-valve 455 cubic inch engines as well. "Hot Rod" Magazine in 1969 also did a nice profile of the twin turbocharged all aluminum Oldsmobile 455 engines designed for Oldsmobile’s foray into Can Am racing.
